Commit data in a mysql container

Question

I created a mysql container using the officially supported mysql image. I ran the image mounting a folder that contains a sql dump, then I created a new database in the cont

Based on @Robert answer, I ended up with this Dockerfile:

FROM mysql:5.6.22

RUN cp -r /var/lib/mysql /var/lib/mysql-no-volume

RUN sed -i -e "s|/var/lib/mysql|/var/lib/mysql-no-volume|" /etc/mysql/my.cnf

The CMD override didn't work for me, container stopped with a strange error:

2019-02-21 15:18:50 1 [Note] Plugin 'FEDERATED' is disabled.
mysqld: Table 'mysql.plugin' doesn't exist
2019-02-21 15:18:50 1 [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.

I guess that the original CMD command was doing more things that is now missing (in @Robert answer) so I did it in a different approach. I didn't try it with latest version but I think it should work.
